I'm trying to run the package posum (http://www.maths.bath.ac.uk/~sw283/simon/posum.html), which is an old package and therefore relies on an old version of the package mgcv (version 0.8-7). I'm trying to run these packages using R version 3.1.0 on windows 8 computer( x86_64-w64-mingw32/x64 (64-bit)). When I run the example code given in the posum package I get an error. The code I'm trying to run is: data<-population.data(fam="p",adult=TRUE) #simulate data b<-posum(data,fam="p") The second line gives an error and a warning: Error in .C("spline_coef", method = as.integer(method), n = n, x = as.double(x), : "spline_coef" not available for .C() for package "stats" In addition: Warning message: In if (d < 0) stop("d can not be negative in call to null.space.dimension().") : the condition has length > 1 and only the first element will be used The part of the posum code that this error refers to is the following: cm.splinefun<-function(x, y = NULL, method = "fmm",gulim=0) # modification of base package splinefun to produce co-monotonic #interpolant # by Hyman Filtering. if gulim!=0 then it is taken as the upper # limit on the gradient. { x <- xy.coords(x, y) y <- x$y x <- x$x n <- length(x) method <- match(method, c("periodic", "natural", "fmm")) if (is.na(method)) stop("splinefun: invalid interpolation method") if (any(diff(x) < 0)) { z <- order(x) x <- x[z] y <- y[z] } if (method == 1 && y[1] != y[n]) { warning("first and last y values differ in spline - using y[1] for both") y[n] <- y[1] } z <- .C("spline_coef", method = as.integer(method), n = n, x = as.double(x), y = as.double(y), b = double(n), c = double(n), d = double(n), e = double(if (method == 1) n else 0), PACKAGE = "stats") z$y<-z$y-z$x*gulim # trick to impose upper z$b<-z$b-gulim # limit on interpolator gradient z<-hyman.filter(z) # filter gradients for co-monotonicity z$y<-z$y+z$x*gulim # undo trick z$b<-z$b+gulim # transformation z<-spl.coef.conv(z) # force other coefficients to consistency rm(x, y, n, method) function(x) { .C("spline_eval", z$method, length(x), x = as.double(x), y = double(length(x)), z$n, z$x, z$y, z$b, z$c, z$d, PACKAGE = "stats")$y } } And finally: > sessionInfo() R version 3.1.0 (2014-04-10) Platform: x86_64-w64-mingw32/x64 (64-bit) locale: [1] LC_COLLATE=English_United Kingdom.1252 LC_CTYPE= English_United Kingdom.1252 [3] LC_MONETARY=English_United Kingdom.1252 LC_NUMERIC=C [5] LC_TIME=English_United Kingdom.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] posum_2.0-0 mgcv_0.8-7 loaded via a namespace (and not attached): [1] tools_3.1.0 I hope this is a more acceptable formulation of the problem!
